These guides are pirotally mounted eaeh at; one end, the mount-ine' preferably being` euch that the guides may Swing: or be oseillated about th` axis et the sand roll. but thin relation to the .aand roll iS noteeeential. This pivotal mounting' ot the guides may be ot- Ateeted in a. great variety olf Ways; o tY wliiih only one ie herein illustrated. The illustrated method of mounting the guidey coinpriseu the provieion toi' eaehggguide ot a member 2t eneirelingl the end et the Sand roll, rotatable upon the roll and .f-eeated preterably on a red need portion 22 thereot.

'.llhe angle o t movement ot the guides approximately 90 and it in advisable to limit the movement substantially to this angle. (lne ronvenient method ot thus limiting the angle ot movement is to provide Stops 2G and 2T on the toothed member or guide in position to engage the ehazt'tll or pinions 2t, as illustrated. 'the otopaA Qt uhieh limit the upward movementA ot the gejuidee may be so diepoeed that the guides ivill swine; slightly panti the vertical, so that the. iveiejlit of the eloth roll will serve to hold the stopt` in en- `sragement 1with their ahutmentfu as in l,t`igi|re l.

rlhe operation oi? the device is as tolloue` z-'lhe guides normally extend approximately vertieally upward trom the Sand roll or lean slightly inward from the vertical to the extent permitted by the stops 26 and the cloth roll eore ie supported on ita ende in the ,euide grooves and reste4 by gravity on the aand roll. rlhe eloth passes over the Sand roll and around the wore so that as tho sand roll is rotated it rotatee the cloth roll. At; the. elot-h roll inereastn.A in diameter itey eore rises in the guides. Cloth may bi allowed to aeeuinulate in the roll `until the eore approarhee the upper ende` olf the ruidos or to any leen eine for whit-h there is.; space available in `the loom. thdii'uirily the length ol?

By this morenieut: the eloth roll ie lowered from a position above and at reet upon the .ea-,nd roll to a position ot' support on the guides at one side of the sand roll. The cloth roll may now be moved out until its core is at the extremities ot the guidee. The end elo' eures t8 ot the guide grooves hold the Core of the roll against accidental Withdrawal beyond the ends ot` the guides, the lateral openings 19 being at the lower sides ot the guides. This drawing out movement of the rol-l is for the purpose of disposing the saine entirely clear ot the loom and the length llt] lill) of the guides is therefore designed with due regard tothe width of the loom and the intended diameter of the cloth roll to attain this result. lhen the cloth roll is drawn outzto the extremities ol: the guides the ends of its core will drop through the lateral openings 19 and into lsuitable receptacles, designated 28 and 4shown in Tfigure 1, which may be mounted upon a truck or other transporting device. By this means it becomes unnecessary Jfor workmen to lift or otherwise support the weight yoi? the cloth roll so that the danger of the same'being dropped is entirely eliminated. If desired the position of the stops 27 may be such that the guides come to rest atta very slight upward inclina tion from the horizontal, so that when lowered the roll will not run out to the ends of the guides of its own weight but will require to be drawn or rolled out. In this way accidents dueto improperly placed receptacles 28 or tothe absence of same will be avoided. vIt desired, the openings 19 may 1 guides for the ends of said corey pivotallyV supported to swing about the axis o'l' .the sand roll with the periphery of the cloth roll continuously in contact witlithat of the sand roll.
